6-1 Bleeding air
Make sure to bleed air when air is introduced into
the pump.
1) Loose the air bleeding valve (roughly one turn
CCW) with a spanner, etc.
2) Activate the pump.
Air and grease come out from the hole at the
end of the valve.
3) When only grease comes out, stop the pump.
4) Manually tighten the air bleeding valve
clockwise and then rotate it by 20° (5 N•m) to
tighten.
Air and grease often splash out from air bleeding
valve.
Wear safety glasses during air bleeding.
